2.0 InstallationBefore installing the XP-EDH-A2 into a power supply, review your system requirements anddetermine the number of cable assemblies you need to monitor your HFC standby power supplies.

The procedure for installing the XP-EDH-A2 into any supported power supply involves general information,(information that is common to all the power supplies), and information specific to an individual type of power

supply. These installation instructions are divided into two sections to reflect this. It is recommended that youread through the general instructions and then take note of any information specific to your power supply.

Also, installation of this product involves both field installation and the configuration of the system, includingnetwork security, SNMP set-up, and other system provisioning. While those two procedures are handledindependently, they are presented together in the section specific to your power supply.

2.1 General Installation Information for Supported Power Supplies

NOTE:

There are a few basic steps to follow to install the XP-EDH-A2 into supported power supplysites. The steps are either field steps or system configuration steps, and can be performedindependently.

Field installation steps are:

Transponder Placement1.

Disconnecting the DC power2.

Configuring the Interface Card3.

Wiring the battery harness4.

Connecting the power supply interface and measurement cables5.

Confirming the RF drop6.

System configuration steps are:

Provisioning Network Connectivity7.

Configuring the MIBS8.

Setting the DOCSIS configuration file options9.

Completing and Testing the installation:

Verifying the operation10.

Detailed information on each of these steps follows.

Note the following:

The types and quantities of each power supply type

Number of individual batteries per site (if you plan to increase the number of batteries in thefuture, consider ordering additional battery harnesses)

Length of required battery harness (The standard 4 ft length battery harness is used in the typicalpower supply cabinet where one to three battery strings are mounted in the trays underneath thepower supply shelf. If necessary, a 20 ft battery harness is available)

The required type of interface cards (RPM, USM, USM2.5, etc.)

Utility power available at the site, 110V or 220V.


11/40

11745-838-B2-001 Rev. A

2.0 Installation, continued

2.1 General Installation Information for Supported Power Supplies, continued

2.1.1 Transponder Placement

Place the transponder on the shelf inside the cabinet next to the power supply.Do not place the transponder on top of the power supply.

Maintain access to the front of the transponder to ease the connection of thecables.

Ensure the cabinet door can close without damaging the cables.

Route and tie-wrap the cables in an orderly manner.

2.1.3 Configuring the Interface Card

Each power supply contains an interface card which provides the commoncommunication layer between the power supply and the transponder. The settingsneeded for your power supply are located in Section 3.0, "Installation Instructionsfor Specific Power Supplies" .

2.1.4 Wiring the Battery Harness

2.1.2 Disconnecting the DC Power

Place the DC breaker in the OFF position.

CAUTION!

Backup capability is suspended with the DC breaker in the OFF position.

Prior to connecting the cables to the transponder, make all harness connectionsto the batteries and interface connectors on the power supply. See the batterydiagrams for your specific power supply.

Double-check all connections. Incorrect connections may damage thetransponder or the power supply. Correct connections at the batteries areextremely important to the proper operation of the power supply.

Ensure that the high current carrying cables and jumpers (heavy gauge blackand red cables) remain in direct contact to the battery terminals.

Never place the transponder battery harness lugs between the current carryingjumper/cable lugs and the battery terminals. See the power supply installationmanual for more information.

In some cases there are more battery harness leads than there are batteries.Connect all unused lugs to the same terminal as the V(-) lead, the same terminalwhere the heavy gauge black cable from the inverter is connected. This preventsstray voltages from being detected by the transponder.

CAUTION!

Incorrect connections may damage the equipment and invalidate the warranty. Double-check all connections.

NOTE:

Depending on the type of enclosure and the power supply you are using, it may be necessary to orient theService Power Inserter (SPI) vertically to provide space for the transponder. Re-torque the SPI to spec (130in/lbs) if repositioning becomes necessary. This is important, as the output neutral is not tied to ground untilconnected to the SPI /enclosure.


12/40

12 745-838-B2-001 Rev. A

2.1.6 Confi rming the RF Drop

An RF drop is required at the power supply site. The RF drop should not haveplant voltage.

The transponder contains a DOCSIS 2.0 cable modem. The downstream level(DS) into the transponder should be between -15 and +15 dBmV, with a recom-mended level of 0dBmV.

2.1.7 Provisioning Network Connectivity

The transponders cable modem must be recognized by the CMTS as a valid device,obtain an IP address from the DHCP server, locate the TFTP and TOD servers, andcommunicate with the SNMP management server (trap receiver). Different securitymethods are used to insure network integrity, some common issues are:

A subscriber account (where the subscriber is the transponder) may be requiredfor each transponder.

The transponders MAC address may have to be pre-loaded into the CMTS.

MAC filtering may have to be modified to allow MAC addresses starting with00:03:08xx:xx:xx to be registered.

For SNMP access, UDP ports 161 & 162 must not be blocked.

Firewalls must allow communication between the cable modem and the variousservers noted above.

If the address of the TFTP and/or TOD server is different than the DHCP server,the response from the DHCP server must contain the TFTP and TOD addresses.

2.0 Installation, cont inued


2.1.5 Connecting the Power Supply Interface and Measurement Cables

Connect the power supply interface and measurement cables to the powersupply. Connections are dependent on the type of power supply configuration

you are using. See the section specific to your configuration.It is important to be able to measure the site input line voltage. If you arenot using a USM2.5/XM2 power supply, then it is recommended you use atransformer (110V and 220V available*) to sample the commercial power atthe site. While it does not power the transponder, it makes it possible for thetransponder to report the actual line voltage. An additional transformer is notnecessary when using a USM2.5/XM2 power supply.

Use a surge protector within the cabinet when you are using a transformer tomeasure line voltage. Most cabinets come equipped with a duplex outlet.

* 110V applications: CBL-PS-PWR-01-001, p/n 875-563-10220V applications: CBL-PS-PWR-03-002, p/n 875-562-10(3' cord with IEC C13 connector and 220V US NEMA 6-15 plug)

2.1.8 Configuring MIBs

This step is not performed in the field, but at the network end of the installation.

There are two propriety MIBs (Management Information Base) from Networksneeded to configure the XP-EDH-A2. Refer to Section 4.0, "ProprietaryManagement Information Bases (MIBs)" for detailed information.


13/40

13745-838-B2-001 Rev. A

2.1.10 Verify ing Operation

After the connections are complete and the transponders online LED is on solid,indicating network connectivity, verify the site is visible on the appropriate cable

modem or computer network, and that all parameters being monitored are visibleand accurate.

Any standard Web browser on a personal computer configured for networkconnectivity to the transponder should be able to read the XP-EDH-A2Web interface by simply pointing the Web browser to the IP address of thetransponder (for example, ht t p: / / 10. 1. 3. 65) .

Confirm that all cable harnesses are neatly dressed within the enclosure.

Verify that you can close the cabinet door, and move the battery tray in and out,without contacting or damaging any of the cables.

3.0 Installation Instructions for Specific Power SuppliesThese are specific installation instructions for standby power supplies supported by the XP-EDH-A2transponder. Each set of instructions include the interface card settings, a system diagram, and theoutput voltage calibration needed to successfully operate.

NOTE:

All settings and instructions specified here supercede information found in previous manuals.

3.1 Alpha XM2 Series

ATTENTION:

Alpha's XM2 power supply installations using USM2 (both new and old versions) and USM2.5 cards require

switch/jumper settings to be made for proper operation.

1. Determine the characteristics of the power supply, such as the inverter voltage (36V or48V), and the maximum capable output current (typically 20A).

2. If commercial power is present at the site and the power supply is currently beingpowered by commercial AC line voltage, turn the battery breaker OFF on the invertermodule.

NOTE:

When monitoring commercial line power, the XM2 (with the USM2.5 card) does not require an input voltagetransformer because the USM2.5 card provides a scaled voltage representing the line input to the powersupply. In this situation, the transponder makes the measurement via the interface cable connected to theUSM2.5 card.

3. Slide the inverter drawer out to gain access to the switches or jumpers located on thevarious types of USM2 and USM2.5 cards. If you need to install a USMx card, refer tothe manual supplied with the card and complete the installation process.

4. Refer to the following diagram and adjust the switch settings to match your powersupply.

5. Re-insert the inverter module and tighten the retaining screws.

NOTE:

Turning the battery breaker OFF disables standby power.

NOTE:

The EDH-A2 supports AC Scaling for Output Voltage measurements as opposed to DC scaling for the EDH-A.As a result the USM2/USM2.5 switch settings are different and calibration is no longer necessary. Refer tothe EDH-A Installation Manual for EDH-A installation procedures.

3.0 Installation Instructions for Specific Power Supplies, cont inued

3.3 Alpha AM/AP Series Power Supply

If commercial power is present at the site, and the power supply is currently powered1.by commercial AC line voltage, turn the battery breaker OFF on the power supply anddisconnect the power supply from utility power.

If not already installed, install the RPM card. Refer to the instructions that come with this2.assembly.

WARNING!

Installing the XP-EDH-A2 transponder at an Alpha AM power supply site requires shutting

down the power supply. If a short power interruption is not feasible, you must use analternate source of system power during the installation of the transponder. This isnecessary to install the RPM interface card, and to make connections to the output of thepower supply to permit monitoring of the output voltage of the power supply.

If a short power interruption is not feasible, you must use an alternate source of systempower during the installation of the transponder.

3.3.1 Connecting the XP-EDH-A2 to an AM/AP Series

Follow Fig. 3-9 to make connections between the transponder, the power supply siteand battery string.

NOTE:

The RPM card cannot be installed while the power supply is running on utility or battery power.

3.4 Alpha/Lectro ZTT+ Series Power Supply

There are two models of the Lectro ZTT+Series power supply inverter modules. You caneasily identify one type from the other by checking the round 6-pin DIN connector located onthe lower left side of the front panel:

Early units have a solid black DIN connector (pre-1998).More current units have a silver band around the DIN connector.

Early (pre-1998) unit with solid blackconnector

Current unit with silver band on connector

Fig. 3-10, Lectro ZTT+Series Power Supplies

Procedures for installing the XP-EDH-A2 with both types of Lectro ZTT+Series powersupplies follow and are differentiated by a silver or black designation.

3.4.1 Alpha/Lectro ZTT+ Installation (Silver and Black)

If commercial power is present at the site and the power supply is currently1.powered by commercial AC line voltage, turn the battery breaker OFF on thepower supply and disconnect the AC utility power.

Installing the XP-EDH-A2 transponder at Alpha/Lectro ZTT+, or ZTT sites requires temporarily disconnectingthe output of the power supply to the cable plant to insert one of the transponder harnesses in series with thepower supply output. This is necessary so the transponder can measure both the output voltage and outputcurrent.

If a short power interruption is not feasible, you must use an alternate source of system power during theinstallation of the transponder.

CAUTION!

Locate the transponder interface cable with the 6-pin type DIN connector. This2.harness has a selectable switch near the silver 6-pin shell. P lace the switch inthe ZTT+Silver position or in the Black position depending on what type of powersupply you are using.

Make all other harness connections following the diagram in Fig. 3-11.3.

If a site tamper switch is employed, connect the two lugs within the harness to4.the connections on the door switch.

Restore AC utility power and place the DC breaker back to the ON position.5.

NOTE:

Turning the battery breaker OFF disables the standby power supply.
